On May 22, 2013, GOES-East, a key weather satellite that observes the eastern part of the United States stopped working normally. After initial efforts to revive the satellite failed, National Oceanic and Atmospheric Administration (NOAA) engineers have put the satellite in storage mode for troubleshooting. Losing one of the two geostationary weather satellites that National […]
When I heard that student volunteers were needed for IFloodS, I knew I wanted to take part. I had had little experience with fieldwork in the past. Most of my graduate work has been spent in front of a computer, conducting data analysis and performing hydrological modeling. I had difficulty visualizing the information I was […]
New Status: Russian Treadmill (БД-2) Outfitting: ISS Commander (CDR) Vinogradov and Flight Engineer (FE)-2 Misurkin completed the installation of the БД-2. Ground specialists will evalaute pictures and a video that the crew downlinked earlier today. The crew is scheduled to perform a БД-2 checkout tomorrow. Capillary Flow Experiment (CFE) Vane Gap-1 (VG-1): FE-3 Cassidy used a CFE-2 …
Each month, Earth Observatory offers up a puzzling satellite image here on Earth Matters. The sixteenth puzzler is above. Your challenge is to use the comments section to tell us what part of the world we are looking at, when the image was acquired, and why the scene is interesting. For instance, what do you […]
New Status: Fundoscope Activation, Checkout and Eye Exam: Flight Engineer (FE)-3 Cassidy checked out the new Fundoscope hardware used in the Prospective Observational Study of Ocular Health. Following this activity, he performed an eye exam using the fundoscope with assistance of a physician on the ground. Ocular Health’s protocol gathers physiological data to characterize the …
New Status: Multi-user Droplet Combustion Apparatus (MDCA) Hardware Replacement: On May 16, Combustion Integration Rack (CIR) experienced a failed igniter in the combustion chamber. Further test points could not be accomplished until it was replaced. Today, FE-3 Cassidy reviewed procedures, gathered hardware, accessed the CIR Combustion Chamber and removed the MDCA Chamber Insert Assembly (CIA) from the …
Finding a location for two of the four University of Iowa XPOL radars was easy. They will remain at their current home base locations near Iowa City and Cedar Rapids overlooking the Clear Creek Watershed for the IFloodS campaign. For the other two destined for the Turkey River basin in northeast Iowa — well, there […]
New Status: Binary Colloidal Alloy Test (BCAT)-4: Cassidy configured and deployed the BCAT-4 sample module. The BCAT-4 module is being revisited after being undisturbed for several years to see the condition of the sample and their mixing status. BCAT-4 is an experiment of two samples containing microscopic spheres suspended in a liquid which are designed to …
New Status: Automated Transfer Vehicle (ATV) Proximity Communication Equipment (PCE) Installation: FE-2 Misurkin installed and successfully checked out the PCE equipment required for ATV4 docking. A successful checkout of the РСЕ and Antenna Switching Controller (БУАП) in the Service Module is needed prior to the ground fueling the ATV4 tanks, which is scheduled to launch …
